CRFK cells will be grown in Cell Culture Media (Eagle's Minimum Essential Media containing $5% Fetal Bovine Serum) containing Fetal Bovine Serum (FBS). The FCV will be grown by inoculating confluent cell monolayers, no more than 24-48 hours in age, using low multiplicity of infection (MOI). Briefly, a flask of host cells grown in cell culture media containing 10% fetal bovine serum (FBS) will be used. The percent FBS contained in the stock virus aliquot will be adjusted to yield a minimum of a 5% organic soil load. Cells will be washed three times with phosphate buffered saline (PBS) and inoculated with virus. Post-virus adsorption, the cell monolayer will be washed once in Earle's balanced salt solution (EBSS), re-fed with cell culture media and incubated. The cytopathic effects (CPE) will be described as small, rounding of the cells, with a slight granular look. The CPE will start to develop in 1-2 days following inoculation, and will be harvested when more than 90% cytopathic effects (CPE) are observed. Post-incubation, the cells will be disrupted, with cell debris removed by centrifugation. Stock virus will be prepared by collecting the supernatant culture fluid from 75-100% infected culture cells. The supernatant will be removed, aliquoted, and stored in an ultra-low temperature freezer until the day of use.

The virus will be air-dried at room temperature for 30-60 minutes (until visibly dry). The drying conditions (temperature and humidity) will be appropriate for the test virus to obtain maximum survival following drying. The actual drying time and temperature will be recorded. Two carriers will be prepared for each lot of test agent and plate recovery control. Additionally, one carrier per test agent lot will be prepared for the neutralizer effectiveness control using cell culture media in place of stock virus.

C. Test agent preparation: The test agent will be prepared and used according to the Sponsor's directions or proposed label claims.

D. Test: For each of two batches of test substance, two dried virus films will be exposed to 2.0 ml of the use dilution of the test substance, or to the amount of spray released under use conditions (spray products) for a specified exposure time and temperature. Post contact time, the test agent will be neutralized and the mixture will be scraped from the surface of the dish. This will be considered approximately one log₁₀ dilution.

1. Sephadex™/Sephacryl™ Filtration. If columns are utilized, each sample will be loaded into individual pre-spun Sephadex™/Sephacryl™ columns. Virus-test substance mixture will be passed through individual columns utilizing the syringe plunger or centrifugation in order to detoxify the mixture. The aseptically collected samples will be diluted as appropriate.

2. If columns are not used, serial tenfold dilutions of neutralized virus will be prepared in cell culture media. For spray-type agents, the agent will be used as per Sponsor's instructions, the volume produced by the spray product during the spraying application specified by the sponsor will be measured prior to testing and an equivalent quantity of the neutralizer will be applied post contact time. Following application of the test agent, contact time, and neutralization, the procedure for processing the samples will the same as described earlier (see above).

E. Infection, cell maintenance and infectivity assays: Selected dilutions of the neutralized inoculum/test agent mixture will be added to cultured cell monolayers. Four wells per dilution will be added to the host cell monolayers and incubated at 37±2° C. in 5±1% CO₂ for 5-7 days. Post incubation the infectious FCV will be scored microscopically by observing virus-specific cytopathic effects (CPE) produced by replicating infectious virus. The CPE associated with FCV is visually evidenced under the microscope by the presence of small, shrinking cells that have detached from the monolayer. These changes will be scored in comparison with the negative control (cell viability control).

F. Controls: All controls will be performed at the same time as the test, incubated under the same conditions and assayed in the same manner as the test (see above). Neutralizer effectiveness control, Cytotoxicity control and Cytotoxicity-related viral interference control will be performed for test agent(s).

1. Cell viability control This control will demonstrate that cells remain viable throughout the course of the assay period. In addition, it will confirm sterility of the cell culture employed throughout the assay period. Four wells will receive cell culture media only.

2. Virus stock titer. The challenge virus will be titered at the time of the test to determine the relative infectivity of the virus and to demonstrate the susceptibility of the host cells to support infection of FCV. The virus inoculum will be serial diluted tenfold in cell culture media. Selected dilutions will be inoculated into four wells per dilution and incubated under the same conditions as the test.

3. Plate recovery control (PRC). Two ml of cell culture media will be added to the dried virus. Post-contact time, the virus/cell culture mixture will be subjected to the identical neutralization procedure as the test agent. If columns are used, a portion of the virus/cell culture media/neutralizer mixture will be used for the column titer control (see below). This control will determine the relative loss in virus infectivity resulting from drying and neutralization alone. The results from the PRC will be compared with the test results to confirm recovery of at least four log₁₀ of infectious virus following drying and neutralization. Its titer will be used to compare with the titers of the test results to reach the acceptable test criteria (see below).

4. Neutralizer effectiveness control (NEC). The neutralization procedure will be dependent upon the active ingredient present in the test agent and in the internal control test agent. For this control, each lot of the test agent will be processed exactly as the test procedure, but instead of the viral inoculum, cell culture media will be added. Post neutralization, the sample will be divided into three portions [two for cytotoxicity related controls (see below) and one for neutralizer effectiveness].

If columns are used, each sample will be passed through individual columns and the eluate will be serial diluted as appropriate in cell culture media. If columns are not used, the neutralizer effectiveness samples will be serial diluted tenfold in cell culture media. The diluted samples will be mixed with low titer virus, held for a period equivalent to contact time and assayed for viral infectivity and/or cytotoxicity (see below), in order to determine the dilution of test agent at which virucidal activity, if any, is retained. Then the selected dilutions will be used to inoculate host cells as described for the test procedure. Dilutions that show virucidal activity will not be considered in determining reduction of viral infectivity by the test agent.

5. Cytotoxicity control (CT). A CT control will be run to determine if the product is toxic to the cells. Each lot of the neutralized test agent will be run to determine cytotoxicity. The CT sample, acquired from the NEC, will be serial diluted tenfold in cell culture media, having no virus added. Selected dilutions will be inoculated and incubated in the same manner as the test and control samples.

G. Calculations. Viral and cytotoxicity titers will be expressed as -log₁₀ of the 50 percent titration endpoint infectivity (TCID₅₀), respectively, as calculated by the method of Spearman Karber.

-Log of 1^(st) dilution inoculated -[(Sum of % mortality at each dilution/100)−0.5)×(logarithm of dilution)]

The log₁₀ reduction in infectivity will be calculated using the revised EPA approved method for calculating the Most Probable Number (MPN) as obtained from the EPA on Jan. 4, 2001.

EXAMPLE 3 Testing of Efficacy in Different Environments and Against Multiple Pathogens

The cleaning composition of the present application is tested for effectiveness according to EPA standard operating procedures to measure the effectiveness of hard surface disinfectants against Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella choleraesuis, Mycobacterium Bovis, Clostridium difficile, and viruses. The standard operating procedures are based on strict interpretations of AOAC International and ASTM International standard methods.

In an exemplary test, the cleaning composition of the present application is tested as a germicidal spray product with testing for effectiveness against Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella enterica (EPA Method ID: MB-06-08 dated Sep. 22, 2014).

Test cultures of the bacterium are prepared as follows: Defrost a single cryovial at room temperature and briefly vortex to mix. Add 10 μL of the thawed frozen stock (single use) to a tube containing 10 mL of culture medium (Synthetic broth is used for S. aureus, P. aeruginosa and S. enterica. Nutrient broth may be used for P. aeruginosa.). Vortex, and incubate at 36±1° C. for 24±2 h. One daily transfer is required prior to the inoculation of a final test culture. Daily cultures may be subcultured for up to 5 days; each daily culture may be used to generate a test culture. For S. aureus and S. enterica only, briefly vortex the 24 h cultures prior to transfer. For the final subculture transfer, inoculate a sufficient number of 20×150 mm tubes containing 10 mL growth medium (e.g., synthetic broth or nutrient broth) with 10 μL per tube of the 24 h culture then vortex to mix. Incubate 48-54 h at 36±1° C. without shaking.

Carrier inoculation is carried out as follows: Inoculate approximately 80 carriers; 60 carriers are required for testing, 6 for control carrier counts, and 1 for the viability control. For P. aeruginosa, remove the pellicle from the broth either by decanting the liquid aseptically into a sterile tube, by gently aspirating the broth away from the pellicle using a pipette, or by vacuum removal. Avoid harvesting pellicle from the bottom of the tube. Transfer test culture after pellicle removal into sterile 25×150 mm test tubes (up to approximately 20 mL per tube) and visually inspect for pellicle fragments. Presence of pellicle in the final culture makes it unusable for testing.

For S. aureus and S. enterica, using a vortex-style mixer, mix 48-54 h test cultures 3-4 s and let stand 10 min at room temperature before continuing. Remove the upper portion of each culture (e.g., upper ¾ or approximately 7.5 mL), leaving behind any debris or clumps, and transfer to a sterile flask; pool cultures in the flask and swirl to mix.

For S. aureus, P. aeruginosa and S. enterica, using a vortex-style mixer, mix 48-54 h test cultures 3-4 s and let stand 10 min at room temperature before continuing. Remove the upper portion of each culture (e.g., upper ¼ or approximately 7.5 mL), leaving behind any debris or clumps, and pool culture into a sterile flask; swirl to mix. Measure and record the OD at 650 nm. Use sterile broth medium to calibrate the spectrophotometer. Note: To achieve mean carrier counts within the appropriate range (see section 8), the final test culture may be diluted (e.g., one part culture plus one part sterile broth) prior to the addition of the OSL to the inoculum using the sterile culture medium used to generate the final test culture (e.g., synthetic broth). Use the diluted test culture for carrier inoculation within 30 min. Add appropriate amount of organic burden if required. Swirl to mix.

Vortex-mix the inoculum periodically during the inoculation of carriers. Use a calibrated positive displacement pipette to transfer 0.01 mL of the culture to the sterile test carrier in the Petri dish. Immediately spread the inoculum uniformly using a sterile loop. Do not allow the inoculum to contact the edge of the glass slide carriers. Cover dish immediately. Dry carriers in incubator at 36±1° C. for 30-40 min. Perform efficacy testing within two hours of drying.

Enumeration of viable bacteria from carriers (control carrier counts) is conducted as follows: Assay dried carriers in 2 sets of three carriers, one set immediately prior to conducting the efficacy test and one set immediately following the test. Randomly select 6 inoculated carriers for carrier count analysis prior to efficacy testing. Place each of the inoculated, dried carriers in a 38×100 mm culture tube or sterile 50 mL polypropylene conical tube containing 20 mL of letheen broth. Vortex immediately −60±5 seconds for P. aeruginosa or 120±5 seconds for S. aureus and S. enterica. After vortexing, briefly mix and make serial ten-fold dilutions in 9 mL dilution blanks of PBDW. Briefly vortex and plate 0.1 mL aliquots of appropriate dilutions in duplicate on TSA or BAP using spread plating. Plate appropriate dilutions to achieve colony counts in the range of 30-300 colony forming units (CFU) per plate. Spread inoculum evenly over the surface of the agar. Plates must be dry prior to incubation. If the serial dilutions are not made and plated immediately, keep the tubes at 2-5° C. until this step can be done. Complete the dilutions and plating within 2 h after vortexing. Alternatively, pool the letheen broth from the tubes with the carriers and briefly vortex. Serially dilute and plate 0.1 mL aliquots of the pooled media (60 mL). The average carrier count per set will be calculated. Incubate plates (inverted) at 36+1° C. for up to 48±2 h. Count colonies.

Disinfectant sample preparation is conducted as follows: For aerosol cans and trigger or pump sprayers, shake the can 25 times prior to use, unless otherwise specified by the manufacturer. Spray the test substance for 10-15 seconds prior to testing to ensure sprayer is operating correctly and test substance is dispensed properly. For concentrated test substances, aseptically prepare the test substance use-dilution required for the test using appropriate sterile glassware or pipettes. For concentrated test substances, use ≥1.0 mL or 1.0 g of the test substance sample to prepare the final solution to be tested. Use v/v dilutions for liquid test substances and w/v dilutions for solids. Prior to testing, wipe the spray nozzle using 70% ethanol and sterile gauze and allow to dry.

The test procedure is conducted as follows: After the required carrier drying time, spray the slides sequentially for a specified time, distance, and number of pumps at timed intervals (typically 30 seconds) with the carriers in a horizontal position. Use a certified timer to time the spray interval. Spray the slide within ±5 seconds of the specified time for a contact time of 1-10 minutes or within ±3 seconds for contact times <1 minute. After spraying, maintain the carriers in a horizontal position. Treated carriers must be kept undisturbed during the contact time. After the last slide of a set (typically 20 slides) has been sprayed with the disinfectant, and the exposure time is complete, sequentially transfer each slide into the primary subculture tube containing the appropriate neutralizer within the ±5 second time limit. Drain the excess disinfectant from each slide prior to transfer into the neutralizer tube. Drain carriers without touching the Petri dish or filter paper. Perform transfers with flame sterilized or autoclaved forceps. The slide can touch both the interior sides of the Petri dish and the subculture tube during the transfer, but avoid this contact as much as possible. After the slide is deposited, recap the subculture tube and shake culture thoroughly. Incubate at 36±1° C. for 48+2 h.

Results are recorded as follows: Gently shake each tube prior to recording results. Record results as + (growth) or 0 (no growth) as determined by presence or absence of turbidity. Confirm a minimum of three positive carrier sets per test. If there are less than three positive carriers, then confirm each carrier.

The cleaning composition of the present application is tested against the parameters set by the EPA in the Series 810—Product Performance Test Guidelines, specifically public health uses of disinfectants (OCSPP 810.2200 (EPA-HQ-OPPT-2009-0150-0029)). To demonstrate efficacy, testing is conducted against Salmonella enterica (S. enterica), formerly designated as Salmonella choleraesuis, American Type Culture Collection (ATCC) 10708 for effectiveness against Gram-negative bacteria, or Staphylococcus aureus (S. aureus) (ATCC 6538) for effectiveness against Gram-positive bacteria. Three batches of the product are tested at the lower certified limit (LCL). For each batch, sixty carriers are used in the test. Three independent tests (i.e., three batches tested once on three different test days) are conducted against the test microbe at the LCL. The performance standard for S. aureus is 0-3 positive carriers out of sixty. The performance standard for S. enterica is 0-1 positive carriers out of sixty. Contamination of one carrier (culture tube) is allowed per 60-carrier set; occurrence of more than one contaminated carrier invalidates the test results. For germicidal spray products, the product should kill the test microorganisms on 59 out of each set of 60 carriers/slides. Contamination of only one carrier (culture tube) is allowed per 60-carrier set; occurrence of more than one contaminated carrier invalidates the test results.

For use as a hospital or healthcare disinfectant, to demonstrate efficacy, testing is conducted against S. aureus (ATCC 6538) and Pseudomonas aeruginosa (ATCC 15442). For use against fungus, to demonstrate efficacy, testing is conducted against Trichophyton mentagrophytes (ATCC 9533). For use against viruses, testing is conducted against Hepatitis B virus, Hepatitis C virus, and Norovirus, the Duck Hepatitis B virus, Bovine Viral Diarrhea virus, and Feline Calicivirus, respectively, which are considered acceptable surrogates for testing.
